IMPROVEMENT IN CARDINGFMACHINES.

Specification forming part of Letters Patent No. 161,252, dated March 23, 1875; application filed October 1G, 1874.

To all whom it may concern:

Be it known that I, JAPHETH MASON, of Taunton, in the county of Bristol and State of Massachusetts, have invented an Improvement in OardingEngines, of which the following is a specification:

The object of my invention is to so construct and secure the tlats7 of a cardingengine as to obviate the diculty heretofore eX- perienced from the warping or twisting thereof.

This improvement is shown in detail in the accompanying drawings, in which Figure l shows so much of the side of a carding-engine as may be necessary to illustrate this invention; Fig. 2, a side view of one of the flats; and Fig. 3, the binderj for securing the screws upon which the iiats rest, and a cross-section of a dat on the line x x, Fig. 2.

A shows the rim of the arch, having the flanges 1,2, and 3; B, the flat, with its stiffening-iron C S S, screws upon which the iiats B rest, and which govern the distance of the flat from the clothing on the cylinder; D, the iingers projecting from the rim, on which the flats are placed to prevent any lateral motion thereof; E, the metal bushing inserted into the iiat to reduce the friction of the flat upon thefin gers, its outline being shown by the dotted line in Fig. 2; H, the binder; and J the screw, by turning which in the proper direction the binder is brought into action against the screws S S, and thus prevents them from turning and becoming loose by the workin g of the machine.

It is of the first importance, indeed, actually necessary, that the hat should be always true and even, and it has been found difcult, even at great expense, to accomplish this for any length of time, the ilat soon becoming warped or twisted, and requiring to be replaced or repaired.

The iiat here described is made of ordinary pine wood and iron, the last being used to obtain the necessary stiffness.

In the drawings accompanying this specilication he iron strip O is screwed upon the face of the dat, and has upon its under side a rib or ilange, as shown by the open line G in Fig. 2. The fingers or spurs D are cast upon the rim, and upon them the dat is placed. Inv

the motion of the strippen (which vibrates beneath the arch,) at proper times, these dats are raised a certain distance and then drop back upon the fingers as far as the screws S S will permit. The friction ot' the iron nger against the wood often prevents the dat from thus dropping back into its place. To avoid this difiiculty the iat here shown has inserted into it an iron bushing or easing, E, so that the finger D never touches the wood of the iiat, but, coming in contact with the iron bushing only, the friction is but slight, and thus the difficulty is almost entirely overcome.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The dat B, constructed as described, and provided with the metal plate O and the bushing E, as and for the purpose described.

2. In combination with the rim A, and screws S S, the binder H and screw J, substantially as and for the purposes described.
